The Full Description

The Montane Flux Jacket is a highly technical yet insulating mountain jacket that is ideal for climbers and hikers. It is constructed with a Primaloft Silver Eco fill which is a fast drying insulation that is made from over 50% recycled material. The insulation is supported by the Pertex Classic Eco lining, which shuts out the wind and is showerproof, perfect for anyone who wants a versatile jacket for a range of weather conditions.

Inside the garment, a Peaq synthetic liner makes for a comfortable wear against the skin. It compresses just like down, meaning the jacket can be packed to a tiny size. It fits into a small stuff sack that is just larger than an orange and can be stored in its own pocket. Great for when it heats up during an ascent, when you want to wear less but still have your layer to hand. The Jacket has articulated arms so it doesn't restrain when you are reaching. The Microlight ripstop lining in the rear hem, inner hood and pockets increase durability in areas that need that little bit of extra reinforcement. The zipper is full length and two way with a storm baffle that works in tandem with the adjustable hem to properly keep the wind out.

The Montane Flux Jacket packs two map sized chest pockets and two hand warming pockets, all of which are lined with extra insulation to keep your hands warm. The technical hood is also lined with extra insulation and is perfect for fitting under a mountain helmet. It's a highly technical jacket that doesn't compromise on warmth or comfort - ideal for those adventurers who want a reliable jacket that will keep them warm, comfortable and well equipped to tackle the mountains.

Caring for your Montane Jacket

  • The Flux Jacket uses PERTEX® fabric which contains a Durable Water Repellency (DWR) as the first barrier in keeping you dry. Clean your garment in order to maintain this.
  • Machine wash in warm water at 30°C/86°F with a mild detergent. MONTANE® recommends that you use Nikwax Tech Wash.
  • Do not use fabric softeners or bleach.
  • Drip dry.
  • Your jacket may need occasional re-proofing to restore the DWR. MONTANE® recommends Nikwax TX Direct.
